P3.29
A man pushing a mop across a floor causes it to undergo two displacements.
The first has a magnitude of 150 cm and makes an angle of 120° with the
positive
x
axis. The resultant displacement has a magnitude of 140 cm and is
directed at an angle of 35.0° to the positive
x
axis. Find the magnitude and
direction of the second displacement.
P3.39
Vector
B
has
x
,
y
, and
z
components of 4.00, 6.00, and 3.00 units, respectively.
Calculate the magnitude of
B
and the angles that
B
makes with the coordinate
axes.
P3.46
(a) Vector
E
has magnitude 17.0 cm and is directed 27.0
°
counterclockwise
from the +
x
axis.
Express it in unitvector notation.
(b) Vector
F
has magnitude 17.0 cm and is directed 27.0
°
counterclockwise
from the +
y
axis. Express it in unitvector notation.
(c) Vector
G
has magnitude 17.0 cm and is directed 27.0
°
clockwise from the
−
y
axis. Express it in unitvector notation.
P3.60
The instantaneous position of an object is specified by its position vector
r,
leading from a fixed origin to the location of the point object.
